IM PROVEMENT IN COLTERS.

Specification forming part of Letters Patent No. 207,352, dated August27, 1878 application filed June 13, 1878.

To all whom it may concern:

Be itknown that I, SAMUEL HATHAWAY, of Collins, in the county of Drewand State of Arkansas, have invented certain new and useful Improvementsin Plow-Oolters; and I do hereby declare that the following is a full,clear, and exact description thereof, which will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters of referencemarked thereon, which form a part of this specification.

Figure I is a side view of colter attached to the plow-beam. Fig. 2 is aside view of the colter, plate, and socket. Fig. 3 is a bottom view ofthe plate and socket. Fig. 4 is a bottom view of the socket and amodification of the plate; and Fig. 5, the plate and socket with the keydetached.

This invention has relation to colters for plows; and consists in theimprovements in the construction of the same hereinafter more fullydescribed, and particularly pointed out in the claim.

In the accompanying drawings similar letters of reference indicate likeparts in the invention.

The plate A, provided with the socket 13, having the removable key 0,held in place by .the nut D and bolt E, which passes through the colterF, is secured to the plow-beam in front of the plow G in any suitablemanner. The colter F is provided with a series of holes, H, to receivethe bolt E, and to permit it to be vertically adjusted in its socket B.The key 0 is removable from the socket and occupies nearly the whole ofone side of the same. The

colter F is introduced into its-socket B from the bottom, and the bolt Eis passed through any one of theholes E that will hold it at the desiredelevation. The key 0 is then put to place, and the bolt 0 is passedthrough the hole Iin said key 0, and the nut D is screwed upon it, andthe key 0 is pressed as tightly against the shank of the colter F as maybe necessary to hold it firmly in its socket. If the socket B were castwithout the key 0, the colter F would be held loosely in it, and wouldsoon wear the bolt E through by reason of the play the shank of thecolter would have in its socket.

The plateAin Figs. 1, 2, and 3 is intended to be attached to aplow-beamwhere the landside is in line with the side of the plow-beam.

A modification of the plate is shown in Fig. 4, where the colter andsocket are located in the longitudinal center of the plate A, and areintended to be attached to a plow-beam where the land-side comes in linewith the center of the plow-beam.

Having thus described my invention, what I claim as new and useful, anddesire to secure by Letters Patent of the United States, is-

' In combination, the plate A and socket B, provided with the key 0, andthe vertically adjustable colter F, having bolt E and nut D,substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I hereby aflix mysignature in presence of two witnesses. I

SAMUEL HATHAWAY. Witnesses:

EDWARD R. COTHAM, ARTHUR E. HARRIS.
